with latest versions of @libp2p packages, Usage example won't work anymore because classes aren't exported

[TimDaub]

• this example: https://github.com/libp2p/js-libp2p-bootstrap#usage
• but e.g. for TCP, mplex and other packages the actual classes aren't exported in the latest versions anymore and so this usage example won't work if someone copy pastes it.
